Schneider Electric 58 TRX manual Applications

Altivar® 58 TRX AC Drives

Type FVC Drive Controllers

Applications

The ATV58 Type FVC product is recommended in place of the ATV58 TRX Type H drive controllers in the following applications:

•Applications that require encoder feedback and the installation of an I/O extension card or a communication card

•Applications that require PID regulation of a process loop

•Applications requiring improved open loop torque performance at low speed

•Applications requiring high torque performance at low speed with encoder feedback

•Applications requiring holding torque at zero speed

The ATV58 Type FVC product has the following hardware not supplied with the ATV58 TRX Type H base product:

•Differential analog input, +/- 10 Vdc (+10 Vdc supplied from drive)

•RS422 encoder input, 5 V (max. frequency input: 200 kHz)

•Encoder power supply (5 V, 200 mA)

•A keypad is supplied with the drive controller

The ATV58 Type FVC product has the following software features not supplied with the ATV58 TRX Type H base product:

•Faster motor control algorithm in open loop and closed loop

•PID regulator with trim input

•Motor pre-fluxing options; continuous or by logic input

•Ability to customize the shape of the acceleration and deceleration ramps. Selectable acceleration and deceleration ramp increments are 0.1seconds or 0.01 seconds.

•Ability to use +/- speed trim around a speed reference input

•PI and IP mode of operation for matching initial response time vs.ability to suppress speed overshoot

•Variable torque macro has been removed. No variable torque ratings.

The ATV58 Type FVC drive controller is rated for Constant Torque (CT) applications. Constant Torque applications usually require motor-rated torque through the entire speed range, high transient torque capability, and precise speed regulation.
